ErrorException with in-place updating with function wrapper specialization in debugger environments #905
Description
Summary - Running the following code through the debugger in VS Code fails with
Error Exception: `llvmcall` must be compiled to be called
MWE -
using DifferentialEquations
function lorenz!(du,u,p,t)
du[1] = 10.0*(u[2]-u[1])
du[2] = u[1]*(28.0-u[3]) - u[2]
du[3] = u[1]*u[2] - (8/3)*u[3]
end
function lorenz(u,p,t)
du=similar(u)
du[1] = 10.0*(u[2]-u[1])
du[2] = u[1]*(28.0-u[3]) - u[2]
du[3] = u[1]*u[2] - (8/3)*u[3]
return du
end
u0 = [1.0;0.0;0.0]
tspan = (0.0,100.0)
# Try using lorenz()
prob = ODEProblem(lorenz,u0,tspan) # Works
sol = solve(prob)
println("Completed problem 1")
# Try using lorenz!()
prob = ODEProblem(lorenz!,u0,tspan) # Exception
sol = solve(prob)
println("Completed problem 2")
Details - This code solves example 2 from the documentation using both an RHS that allocates lorenz() and another that uses in-place updating lorenz!().
The in-place updating version fails when run with the debugger in VS Code with the following error
Exception has occurred: ErrorException
`llvmcall` must be compiled to be called
